This is a very easy and delicious recipe. I'm not a fan of sweat potatoes, so I used regular potatoes. I also chopped up the onion so my boyfriend, who is not a fan of onions, would eat them. Next time I make it I will definitely use a pre seasoned pork tenderloin. I've never liked Catalina dressing, but I ate the left over potatoes and onion alone with the Catalina dressing the next day, and it was very good. I will be making this recipe again!
